For example, if you specify the maximum MCS index as 5 for mandatory rates, rates corresponding to
MCS indexes 0 through 5 are configured as 802.11n mandatory rates.
Mandatory rates must be supported by the AP and the clients that want to associate with the AP.
Supported rates allow some clients that support both mandatory and supported rates to choose
higher rates when communicating with the AP.
Multicast MCS: Specifies 802.11n multicast data rates.
Configuring 802.11n rates
Select Radio > Rate from the navigation tree to enter the rate setting page, as shown in Figure 34-10 :
Figure 34-10 Set 802.11n rate
Table 34-6 shows the configuration items of setting 802.11n rate.
